1` j This invention relates to pipes having ash and heel ejectors andthe principal object of the'invention resides in the provision of a pipehaving a bowl and there being an upstanding bushing or the like therein,said bushing forming a well in the body of the pipe and slidablyreceiving. a push rod having thereon a flexible steel ash and heelejection plate and including Van ejector handle which Yis normallyadapted to lie under a part of the pipe in substantially housedcondition, but which may be swung around on a pivot on the ejectorplunger to operate the same rectilinearly to eject material from thebowl of the Dlpe. Y

Further objects of the invention include the provision of apipe as abovestated including a cover firmlyA secured tothe plunger and covering thebushing so asto prevent entrance of tobacco iuice and particlesthereinto; the provision of the device as aforesaid including a heatresisting rubber shield forming a tight but flexible closure completelypreventing the entry of tobacco juice and particles to the plunger; andthe provision of a pipe of the class described having a. slotted ashejector plate,l the Vsame being flexible and adapted to be'movable'inthe Vpipe evenr though it should tend to stick.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which:

Fig. 1 is a central longitudinal sectional view through a pipe accordingto the presentk invention;

Fig. 2 is a top plan view thereof; Y Fig. 3is afragmentary view inelevation;

Fig. 4 is an enlarged sectional view illustrating the ash ejectorplunger;

Fig. 5 is a top plan view of the plunger;

- Figs. 6 and 7 are detailed views of the plunger` and handle; and

Fig. 8 is an enlarged view in section showing a ball catch for thehandle, said ball catch maintaining the same in housed condition shownin Fig. 3.

In carrying out the present invention, there is provided a more or lessconventional pipe stem I0 which ts into the body I2 of the pipe andwhich may be held therein by a bushing I4. The body I2 is preferablymolded plastic, but may be any suitable material, such as wood, metal,etc.

The body I2 is provided with a bottom longitudinal slot I6 which isadapted to at leastV partially house a lever or handle I8 which extendsrearwardly and is pivoted at 20 to a plunger 22 extending vertically inupright condition in a Y s claims'. (c1. isi- 183) bushing 24 which maybe formed as a part of the body I2 and provides therewith an annularwell 26. The bushing 24 is here shown as made up of two parts ttedtogether, and is provided with screw threads 28 which mesh with likescrew threads on a bowl 30. The portion of the bushing containing thescrew threads 28 is cut out as at 32 to allow the passage of smoke fromthe bowl of the pipe down into the well 26, and a gasket 33 may be usedbetween the bowl and the body I2.

Theplunger 22 is provided at its upperrend with a cover 34, this coverbeing shown in detail in Fig. 4. The plunger 22 is surrounded by acompression spring 36 which provides for correct alignment of the'plunger in the bushing 24 during the ejecting action, i. e.,reciprocation of the plunger. vIt is to be noted that this spring hasbeen inverted in Fig. 4 as compared with the Fig. 1 showing thereof, andthe spring may be assembled in the device in either way. Also, thisspring may be made of thicker or thinner wire depending on choice ordesign, as illustrated in Figs. l and 4.

Above the cover there is provided a thin flex'- ible stainless steelelement 38. This element is slotted radially as at 40, see Fig. 5, forthe purpose of increasing the flexibility thereof so that if it sticksinthe bowl, it may, nevertheless be pushed up to complete the cleaningaction. The diameter of the element 38 is slightly less than that of thebowl of the pipe.

A heat resisting rubber shield 42 may be sealed to the cover 34 as at 44and to an upstanding boss at the bottom of the recessv provided bybushing 24, see 46 in Fig. 4, but this shield'rnay be omitted as shownin Fig. l. A form of silicon rubber is usable for the purposes stated,and the shield may be such as to overcome the action of spring 36.

The handle I8 is maintained in its inoperative position as in Fig. l bya double ball catch arrangement 50, this comprising a pair of ballsspring pressed apart and fitting in a bore 52 of the handle so that theballs yieldingly press upon walls 54 of the pipe part I2 forming a slotfor the reception of the handle I8.

In the operation of the device, after a pipe full has been smoked, it ismerely necessary to grasp the ns on the handle I8, bring the handledown, and move it in an upward direction to clear the pipe bowl. Ifcleaning element 38 tends to stick, itis flexible enough to be rammedthrough the bowl without injury, and as seen in Fig. l, it is clear thatthe element 38 is a little smaller in diameter than the bowl of the pipeto allow a desired degree of caking.

The smoke will pass down past cover 34, through the holes 32, and intothe well 26, and of course the same is true of moisture which is,however, kept away from plunger 22 by the cover 34 and shield 42. Thisshield is not in all cases necessary, but it improves the cleanlinessand sanitation of the pipe. Moisture and detritis will be caught in thewell 26 below the level of the smoke hole 56. Another protection againstmoisture entering the bushing and impinging on plunger 22 resides in thecollar 58 which acts as a barrier. This collar may be integral withcover 34 and has a V-section, the apex of which points downwardly. Itwill be clear that this invention provides a sanitary and clean ashejector which will always remain clean due to the cover 34, shield 42,and other details of the construction of the device.

Having thus described our invention and the advantages thereof, we donot wish to be limited to the details herein disclosed otherwise than asset forth in the claims, but what we claimV is:
